CENTER SILL FOR RAILWAY-CARS.

SPECIFICATION forming part Of Letters Patent NO. 732,442, dated June 30, 1903.

Application filed October 27, 1902.

To all whom it may concern:

Be it known that I, OSWALD S. PULLIAM, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Center Sills for Railway-Cars, of which the following is a full, clear,'and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a center sill formed of an integral casting for railway-cars; and the invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a perspective view of my sill. Fig. II is a top or plan view ofone end of the sill, partly broken out. Fig. III is a side view of one end of the sill. Fig. IV is a cross-section taken on line IV IV, Fig. III. Fig. V is a cross-section taken on line V V, Fig. I. Fig. VI is a cross-section taken on line VI VI, Fig. III. Fig. VII is a section taken on line VII VII, Fig. III.

1 designates the top chord of my sill, which is of a level plane from end to end.

2 is a vertical web extendinglongitudinally from end to end of the sill, and 3 is a bottom reinforcing-chord or truss-rib that forms the base of the web 2. The ends of the sill are bifurcated to form fork arms 4:, between which the tails of draw-heads may be situated. At intervals along each side of the sill are pockets 5,'that are adapted to receive the Serial No. 129,032. (No model.)

cross-sills of the car and in which said crosssills are supported.

6 represents arms projecting from the sides of the sill, near the ends thereof, and adapted to serve as bearings to rest upon the truckbolsters of the car, the arms being flattened at their under sides, so that they will rest evenly upon the bolsters.

7 is the bolster-bearing, integral with the sill at the location of the bolster-bearing arms 6, as seen in Figs. III and VII.

I claim as my invention 1. A railway-car center sill consisting of an integral casting throughout its length and having bifurcated ends.

2. A railway-car center sill, consisting of an integral casting and having bolster-bearing arms projecting from the sides thereof, substantially as set forth.

3. A railway-car center sill, consisting of an integral casting and having bolster-bearing arms projecting' from the sides thereof and bolster-bearing brackets from the undersides of the sill, substantially as set forth.

4. A railway-car center sill, consisting of an integral casting having means for receiving cross-sills arranged at intervals in its sides and having bifurcated ends, and bolster-bearing arms projecting from the sides of the sill, substantially as set forth.

- OSWALD S. PULLIAM.
